Because the allmodconfig logic just sets every symbol to M or Y, it has the effect of always generating a 64-bit config, because CONFIG_PPC64 becomes Y. So to make it easier for folks to test 32-bit code, provide a phony defconfig target that generates a 32-bit allmodconfig. The 32-bit port has several mutually exclusive CPU types, we choose the Book3S variants as that's what the help text in Kconfig says is most common.
Ok then.

I this a good time to update line 34 at the same time: KBUILD_DEFCONFIG := $(shell uname -m)_defconfig ?
